DETAILED DESCRIPTION OF INVENTION

Referring to FIG. 2, an embodiment of a packaging structure of the invention comprises a main body 100 and an auxiliary element assisting the main body 100 to move along a surface.

The main body 100 comprises a first side 110, a second side (handle surface) 120, a bottom (auxiliary element surface) 130 and a third side 140. The first side 110 faces the second side 120, and the first side 110 and the second side 120 are adjacent to the bottom 130. Because the embodiment is rectangular, the third side 140 is also adjacent to the first side 110 and the second side 120, and the third side 140 is also adjacent to the bottom 130. The main body 100 is, however, not limited to a rectangle, a polyhedron is also applicable to the invention. In a polyhedron, the third side 140 is not necessarily adjacent to the first side 110 and the second side 120.

The auxiliary element comprises a cord 200 and a cylinder (pad body or ring member) 300, as shown in FIG. 3. One end of the cord 200 is fixed to an inner wall of the main body 100 by a fastener 500, the inner wall corresponding to the first side 110, in this embodiment. The other end of the cord 200 traverses across the bottom 130 and winds around a fastener 600 which is T-shaped and fixed to the second side 120. Accordingly, one end of the cord 200 is fixed to the main body 100 and the other end is detachably fixed to the main body 100 by winding around the fastener 600, whereby the elasticity of the cord 200 is adjusted.

The cord 200 extends through the cylinder 300 and along the axis of the cylinder 300. The cylinder 300 shown in FIG. 2 has a gap 310 which is formed on the periphery and parallel to the axis of the cylinder 300. The cord 200 enters a hollow portion 320 through the gap 310, whereby the cylinder 300 is secured on the bottom 130 and positioned thereon by winding the cord 200 around the fastener 600.

The cord 200 and the cylinder 300 can be accommodated in the main body 100 first. When the package is employed to accommodate an electronic device, the cord 200 and the cylinder 300 are taken out of the main body 100. The cord 200 is secured on the bottom 130, the cylinder 300 engaged with the cord 200 and the elasticity of cord 200 adjusted. When the package is transported, a handle 400 on the second side (handle surface) 120 is pulled by hand, and the package moves along the surface with the cylinder 300 contacting the surface.

If the surface is smooth, the cylinder 300 slides, whereby the main body 100 moves along the surface. If the surface is not smooth, the cylinder 300 rolls on the surface, whereby the main body 100 moves on the ground.

In addition, the cord 200 can be soft or rigid. If the cord 200 is soft, the main body 100 is supported by the cylinder 300. If the cord 200 is rigid, the cord 200 supports the main body 100.

FIG. 4 depicts another embodiment of the invention. On the main body 100, a cylinder (pad body or ring member) 800 is disposed at the junction of the bottom 130 and the third side 140. The cylinder 800 can be fixed on the junction of the bottom 130 and the third side 140 permanently by a fastener (not shown), such as a shaft fixed between the first and second sides 110 and 120. The cylinder 800 can also be detachably fixed thereon as with the previous embodiment.

When the package is transported, as shown in FIG. 5, a handle 400 on the package is pulled by hand to incline the main body 100 at an appropriate angle with respect to the surface, and the package moves along the surface with the cylinder 300 rolling.

Although a cylinder is described here, the embodiment, it is not limited thereto. Elements which can rotate about the cord 200 and roll on the ground are applicable, such as a wheel.

FIG. 6 depicts another embodiment of the invention. On the main body 100, a metal sheet (sliding member) 900 is disposed on the junction of the bottom 130 and the third side 140. When the main body 100 is pulled, the main body 100 moves along the surface with the metal sheet 900 sliding along the surface. The metal sheet can be curved, as shown in FIG. 7, to reduce friction. Although a metal sheet is described here, the embodiment, it is not limited thereto. Hard-wearing material with low friction coefficient is applicable.

While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
